Ruby

Ruby (Japanese: ルビー, Rubī), is a hare character from the Japanese company Sanrio, created in 2008 as a collaboration with Sega Toys Co., Ltd. She is specifically based on the Japanese hare and is one of the mascots of the Jewelpet franchise, debuting as one of the original 33 Jewelpet creatures.

Ruby would go on to star in the Jewelpet anime series beginning the following year, taking over the timeslot that Onegai My Melody had held across its four seasons. Though this would not be Jewelpet's only connection to Onegai My Melody, as in 2012 a special short: "Onegai My Melody: Yū & Ai", was screened alongside Jewelpet the Movie: Sweets Dance Princess, the first movie in the franchise. This short featured a guest appearance from Ruby.
